# Cortex Mediator Demo API

This is a demonstration project showcasing the implementation of the Cortex Mediator pattern in a .NET API application. The project serves as a practical example of using Cortex Mediator as an alternative to MediatR for implementing the mediator pattern in .NET applications.

## Key Features and Technologies

- Built with .NET 9.0
- Implements CQRS (Command Query Responsibility Segregation) using Cortex Mediator
- Integrates Serilog for comprehensive logging
- Features cross-cutting concerns through Pipeline Behaviors
- Implements Notification Pattern for event handling

## Core Components

1. **Command and Query Handling**
    - Book Purchase functionality through commands
    - Book retrieval by ID through queries

2. **Pipeline Behaviors**
    - Logging behavior for tracking all commands and queries
    - Notification behavior for handling specific command events

3. **API Endpoints**
    - GET endpoint for retrieving books by ID
    - POST endpoint for creating new book entries

## Technical Benefits

- Clean separation of concerns
- Enhanced maintainability through single-responsibility components
- Reusable pipeline behaviors
- Flexible architecture allowing easy modification
- Testable components that can be verified in isolation

## Testing Capabilities

The project includes HTTP request tests and comprehensive logging features, making it easy to verify functionality and track system behavior. Logs are stored in a dedicated folder with daily rolling intervals.
This implementation demonstrates a modern approach to building scalable and maintainable .NET APIs using the Cortex Mediator pattern, making it an excellent reference for similar projects.
